So the springs that came with my Edelbrock heads need to be changed because I am using a Comp cam?

Any of those companies to prefer before the other?

Comp Cams 26918 is the spring that fits Vortec heads without any machine work. The Lunati 74818 looks to be identical, but I might have missed something?
